 So let's see the error. The error is script inherits from native type something. So it can't be instance in object of type something else. So this error happens whenever you attach a script to a node, but the first line of your script has a name of a node that doesn't correspond with the type of the node that you're attaching it to. In this case, we see here in the script we use the rich text label node, but this is a regular control node. So a way to fix this issue would be to change this to control. So that way when we run the game, it runs normally or to go back and change this node to a rich text label. That way, both the node here and the script that is attached to have the same name. Of course, this is not only exclusive to this kind of nodes. It can happen to everything. So if we use pride as an example, the same error will show up, but with different names here. In this case, this is the rich text label and now this is the sprite. If you're unsure about the type of node that you're dealing with, you can go here to the inspector and you will see the name of the node on the first line of the properties because since we are able to change the names of the nodes, we can see here that this is not the name that the script is looking for. This is the name that you have to get as well on the extents.
